It refers to the latest (at the time of posting) episode of the Geographical Association's GeogPod podcast - hosted by John Lyon. I've posted about that previously. This is the 70th episode of the PODCAST, which is an impressive achievement.
This talks about an opportunity for those living near a Chalk Stream to take part in the Chalk Stream Challenge.
This has been developed with the Hampshire and Isle of Wight Wildlife Trust.
From the website:The challenge is suitable for Scouts, Guides, and similar groups. It involves activities that can easily be customised to suit different age ranges. There are several set routes to choose from, all of which are 'off-road’ but close to public transport, parking, and places to find refreshments and toilet facilities.
The Chalk Stream Challenge was created by two brilliant volunteers, Hazel and Sarah, as part of the Watercress and Winterbournes Landscape Partnership Scheme.
This might make a suitable field activity for GCSE Natural History students in time.
